A cylinder rolls up an inclined plane, reaches some height and then rolls down (without slipping throughout these motions). The directions of the frictional force acting on the cylinder are
Options:
Answer:
B
Solution:
See given the figure.
It is obvious from figure, that during ascending, a retarding, i.e. anticlockwise moment is required. It should be remembered that torque due to friction has the same sense the angular acceleration.
